Anthurium plant named ‘ANTHDOTXI’

ABSTRACT

A new and distinct variety of  Anthurium  plant named ‘ANTHDOTXI’ particularly distinguished by having large bright red, heart-shaped and very durable spathes that retain the original color for a very long period of time, dark green and cordate, durable leaves, red cataphylls, rich flowering continuously throughout the year and a plant height of 50 cm to 55 cm, is disclosed.

Genus and species: Anthurium andreanum L.

Variety denomination: ‘ANTHDOTXI’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium,botanically known as Anthurium andreanum L., and hereinafter referred toby the variety name ‘ANTHDOTXI’. The new variety originated from ahybridization made in June 2006 in Bleiswijk, The Netherlands. Thefemale parent was a red Anthurium pot plant designated ‘9632-01’(unpatented), and the male parent was a red Anthurium plant designated‘9863-01’ (unpatented).

A single plant was selected in June 2008 and has been asexuallyreproduced repeatedly by tissue culture in Bleiswijk, The Netherlandsover a seven-year period. The present invention has been found to retainits distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety have been applied for in theEuropean Union on Jul. 5, 2013 and in Vietnam on Apr. 10, 2015.‘ANTHDOTXI’ has not been made publicly available or sold anywhere in theworld more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Bleiswijk, The Netherlands:

-   -   1) Large, bright red, cordate spathe;    -   2) White spadix with yellow tip;    -   3) Dark green, glossy, long cordate leaves; and    -   4) Red cataphyll.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctivecharacteristics of ‘ANTHDOTXI’. The data which define thesecharacteristics were collected from asexual reproductions carried out inBleiswijk, The Netherlands. The plant history was taken on 40-week oldplants which were planted from tissue culture in 17-centimeter pots andgrown in a glass greenhouse between 19° C. and 24° C. Observations weremade in July 2015. Color readings were taken under 5000 lux naturallight in the greenhouse. Color references are primarily to The R.H.S.Colour Chart of The Royal Horticultural Society of London (R.H.S.)(2001).

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘ANTHDOTXI’ differs from the female parent plant ‘9632-01’ (unpatented)in that ‘ANTHDOTXI’ has a larger spathe width than ‘9632-01’.

‘ANTHDOTXI’ differs from male parent plant ‘9863-01’ (unpatented) inthat ‘ANTHDOTXI’ has a geniculum that is lighter green than the petiole,whereas ‘9863-01’ has a geniculum that is darker green than the petiole.

‘ANTHDOTXI’ differs from commercial variety ‘ANTHBNZL’ (U.S. Plant Pat.No. 17,134) in that ‘ANTHDOTXI’ has a yellow immature spadix and a redcataphyll, whereas ‘ANTHBNZL’ has an orange-yellow immature spadix and agreen cataphyll. Additionally, ‘ANTHDOTXI’ has a more round spatheshape, whereas ‘ANTHBNZL’ has a more elliptical spathe shape.

‘ANTHDOTXI’ differs from commercial variety ‘ANTHCITOK’ (unpatented) inthat ‘ANTHDOTXI’ has a red cataphyll, whereas ‘ANTHCITOK’ has a greencataphyll. Additionally, ‘ANTHDOTXI’ has shorter leaf lobes than‘ANTHCITOK’ and a less red color in summer on the lower surface of theyoung spathe than that of ‘ANTHCITOK’.

I claim:
 1. A new and distinct variety of Anthurium plant named‘ANTHDOTXI’, substantially as illustrated and described herein.
